The historic cupola at the Galeries Lafayette in Paris.

PARIS — Angling to offer its clients the “department store of the 21st century,” Galeries Lafayette has tapped the same architectural firm that transformed Selfridges in Birmingham, and is currently extending the Victoria & Albert Museum in London.

London-based AL_A, founded and led by Amanda Levete, is to start remodeling works for the 430,000-square-foot unit on Boulevard Haussman in early 2017.

The building’s key feature is its Art Nouveau cupola, which celebrated its 100th birthday in 2012.

The retailer said AL_A was chosen for its “bold proposal” that will create a “visionary metamorphosis” of the department store’s main building.
